MAINTENANCE
INSTRUCTION
STRAINER CLEANING
This information is to help you properly remove and reinstall the strainer on
you’re A\C unit for cleaning. This procedure should be done at least twice per year to
maintain good performance and operation of your A\C unit.
This is a list of tools you will need:
A small pipe wrench, 8” will do
A 3\4 wrench (open and box end)
Channel lock pliers
3\4 socket and ratchet
Teflon tape
A small can (soup size)
Steps to fellow:
1. Turn off unit at the thermostat then close both ball valves to the unit, these valves
have a red handle on them
See figure 1
2. Locate the water supply side, this will have water inlet sticker on the unit.
This is the side the strainer is on. See figure 2
3. Locate the drain fitting on the end of strainer and make sure the small red valve
is in the off possession, then remove the cap (you may need the channel locks for
this) and place the can under the drain. Open the small red valve slowly to release
the pressure on the pipe Note: you should only remove a small amount of water at
this point. See figure 3
4. When pressure and water stop, place the pipe wrench on the main part of the
strainer and the 3\4 wrench on the bolt end of the strainer (see figure 4)
Continued from page 1
4. Turn the wrench counter clockwise and hold the pipe wrench so the strainer will
not move. If you are unable to remove the strainer this way then us your channel
locks and pipe wrench and remove the drain end of the valve (see figure 5).
After removing drain use the 3\4 socket and ratchet in place of the 3\4 wrench
And remove the end of the strainer (see figure 6)
5. After removal of the strainer inspect the screen and clean all debris from it.
6. Reinstall screen back in to the strainer, if the drain has been removed use the
Teflon tape around the threads (figure 7)
7. Once all fittings are back on, open the supply line valve first and slowly. Once
open, check for leaks. If no leaks are found open the return line valve. Once both
valves are open, you my turn on the unit.
